` ICELESS JACKET.

Application filed October 3, 1927.' Serial No. 223354.

This invention relates to iceless jackets or casings for receptaclesadapted for containing food and more particularly is directed to aninsulating jacket adapted to receive a can of ice cream and to maintainthe same in a frozen condition over a considerable period of timewithout the use of ice.

It is a general object of the present invention to provide a novel andimproved form of iceless jacket for ice cream cans and the like.

More` particularly it is an object of the present invention to providean nsulatng jacket for ice cream cans having an inner self-supportingwater-proof lining adapted to maintain the jacket in a distended form sothat the ice cream can may readily be inserted thei-ein.

A feature of the invention coinprises a novel means of securing theupper edge of the inner metal lining to the upper edge of the outerinsulating covering of the ice cream can jacket, whereby water is keptout of the space between the lining and the jacket.

A further feature of the invention resides' in the arrangement of acover for the; inner lining of an ice cream can jacket, which 'cover isadapted to receive a super-cooled fluid for the purpose'of maintainingthe ice cream in the top of arcan, which is placed in the jacket, in asolid condition in spite of any extra radiation which may result, due toan insecurely' closed top onthe jacket.

Other and further feat-ures of the invention are disclosed in theacconipanyng drawing and the following specification, as Will be evidentto those skilled in the art. It will be understood that various changesmay be made in the invention as disclosedwith.- out departing froni thespirit thereof.

Insaid `drawing r Fig. 1 is a side elevation, partially in centralvertical section to show the inner Construction ofthe jacket; y

Fig. 2 is a plan view of the jacket shown in Fig. 1; and

Fig. 3 is a transverse vertical section on line 3-3 of Fig. 2, showingon an enlarged scale, the manner ofsecuringthe outer covering to theinner lining y l In my Patent No. 1,639,4:18, dated August 16, 1927, Ihave disclosed an nsulating casing for ice cream cans, the 'same beingformed ot' a suitable, fiexible, heat-insulating material covered on theinner and'outer surfaces With a water-proof material such as canvas, thewhole beingformed as a bag or sack adapted to receive and-closely engagethe sides of an ice' cream can, suitable flaps being provided to foldover the top of the can to complete the encl'osure.` Suoh ;a jacket ismore or less flexble and Pliable, and while it could be collapsed into asmall space for G shipping, nevertheless offered 'certain difficultieswhen it came to placing the can of ice cream within the acket,"owing toits lack of rigidity and its tendency to collapse. The j y operation ofplacingla can within ,a ,jacket consunies considerable time on' thepartof workmen periorm ng the operation, ,To overcome this dificulty as well,as others the y j present invention hasbeen devised Reterring to thedrawings, itwill be seen that the jacket proper is substantially'identicalwith that described in the above mentioned patent and includesthe tubular body portion 10 formed of an innerlayer of insulatingmaterial 11 such as feltor the like, covered on the inner and outersurfaces with water-proof canvas 12. The bottomlcloses one end of thetubular portion, but the upper end is normally open and 'is providedwith the flaps 14 Conveniently formed as integral extensions of the bodyportion 10 and adapted to befolded down, and overlapped, over the top ofan ice cream can which 'may be arranged in the jacket. The bottom and`flaps are preferably constructed of the same insulatng material as theside wallsof the jacket. u u

To render the jacket rigd and self-supporting so that it will readilyreceive an 'ice cream can, it is provided withaninner 'lining 17 ofsuitable'rigid material. Conveniently, this lining may constitute a caneformed of galvanized or ,tinned iron or the like comprising the ,tubularside walls' 18 and a suitable bottom closure. This can has somewhatlarger diameter in order that it 'may assume a substantially squareconfiguration at the top for convenience in folding over the fiaps, aswill be apparent from F 2.

ince the interior of the can must be Washed occasionally and since it isexposed to moisture from condensation and various other causes, it isdesirable that a watertight connection be made between the upper edge ofthe insulating jacket and the upper edge of thecan to prevent theentrance of water into the space ,20 between these two, which would tendto rot the insulating material; This is accomplished by providing a'circumferenti'al flange 21 near the upper edge of the can.Conveniently, this may be formed' as shown in Fig. 3 by bending the canedge downwardly as at 22 and then outwardly to form the fiange a slightdistance below the upper, edge of the can. A suitable pieceofwater-proof fabric 23, such as canvas or thelik'e, is perforated sothat Vit can be slipped over the can from the bottom and' will abutagainst the under side of the flange. A metal ring or the like 24 is'then placed cover the can and Secured against the canvas 23 by rivetingthe fiange 21, canvas 23, and the ring 24; together by rivets such asshown at 25, thus forming a water-tight joint in a Very simple manner.

' 'In order to fasten theouter edgesof the canvas sheet 23 to thejwallsof the otherwise completed jacket, a strip of water-proof material suchas canvas'26 is sewed around 'to the upper edge of the jacket by meansof the stitches 27 isubstantially along the center of the strip: Thestitches 27 also assist in compressng the insulating material to formaconvenient folding line for the flaps. The upper portion of this stripof canvas 26 is folded down upon itself, so that the upper portion`28thereof lies against the 'lower portion. The outer edges of the canvassheet23 are folded under, and the told is Secured to the fold of thecanvas strip 26,

adjacent its stitching to the body portion of the jacket, by suitablestitches 29 which may be whipped over by hand or otherwise suitablyplaced in position. The stitching material, as wellas the canvas, beingimpregnated with a suitable water-proofing compound, the various seamsjust described are water resistant.` It will be* seen that thecanvasxsheet 23 thus forms a barrier against the entrance of waterbetween the insulating coverng and the rigid water-proof inner lining.The Construction is such that the lining can readily be applied to astandard i jacket of the type described in the applicant s prior patent.e

` It is sometimes found that. aftera long interval the ice cream in acan enclosed in the jacket begins to soften at the top since there issome tendcncy toward air and heat leakage where the fiaps of the jacketoverlap. In the present instance, a means of overcoming this dificultyto a large extent has been illustrated. It comprises a hollow lid 32 forthe lining 17. This lid is of substantial depth and forms the chamber 33whichis adapted to receive a super-cooled liquid such as brine to assistin maintaining the proper temperature of the ice Cream in the can. Theliquid may be placed in and removed from the hollow lid through theopening 34 closed by the pipe-threaded plug 35. The lid fits within theupper end of the lining as .clearly shown in Fig. 1,- and the. radialfiange 36 prevents the same from falling within the lining. It maysometimes be found advantageous to hinge this lid to the lining, inwhich' case a hinge strap, such as 37, is riveted to the top of the lidand cooperates with a hinge section-38 Secured to the fiange 21 on thelining. If desired; the

removable hinge pin 39 may be provided and attached to the lining bymeans of a chain 40. In this manner, the lids can be readily removed forfilling and emptying.

It will be found that the iceless jackets provided With the lining justdescribed can be loaded with cans much more rapidly and can likewise beemptiedmore quickly. Furthermore, the interior, being washable, is muchmore sanitary than the usual fabric interier of the jackets. The metallining offers a suitable protection to the lining against wear resultingfrom constantly inserting andremoving cans which are usually wet and maybe somewhat gritty on the outer surface. p

Having thus describedthe invention, what is claimed as new and desiredto be Secured by Letters Patent is:

trance of water between said parts.
